Well this might bode well for some technical discussion...
Using a neat tool (not sure how accurate) provided by GPUReview, I have calculated the theoretical (it has to be) clocks needed for the GTX 260 to equal the performance of a stock GTX 280.
They are as follows:
Core: 961MHz
Shader: 1625MHz
Memory: 2538MHz
Here is a screenshot I took after using the tool to get these results:

EVGA GTX 260 FTW Edition
And I doubt you would ever get the GTX260 to clock that high.
The 260FTW Edition comes pretty close to it. I think it would be the best option.
# Core clock: 666MHz
# Memory Clock: 2214MHz
It comes real close, But I don't think it will actually *catch up* to the GTX280 due to more memory, wider frame buffer and the fact that you just cannot overclock to 280 speeds.
Very interesting stuff JPB, thank you. I guess this means that the tool at GPUReview isn't so accurate. Also, if the GTX 260 FTW Edition really does equal or slightly surpass the performance of a bone stock GTX 280, then there is really no need for me to consider buying the GTX 280.
First of all, the GTX 280 is not as good as the GTX 260 considering performance/dollar ratio and I'm pretty sure I can buy a stock GTX 260 and take it to FTW clocks, maybe higher. So I guess I have my mind kinda set on a GTX 260 then.
On the other hand, my X48 board should be arriving this week (hopefully tomorrow) so....that opens up a whole new can of worms....What the hell to get?
I think this is the most confusing time ever in the GPU market for people looking to buy now or soon. So many great options at some many great price points, its amazing and confuzing (deliberately spelt it wrong).
Sure the GTX 260 looks great now at $280 but what about the 4850 X2 to debut in a month or so @ $400 (with the price to drop in a few weeks after release). Then there is the option to CrossFireX that with another later on....
Arggggggghhhh.....

Now that's what I'm talking about.
Without really researching the overclocks that people have been getting, I was aiming for something like 700/1500/2400 but I guess I can get even more out of it.
Thanks for the figures bdubyah.
Note: I'm still confused like hell.

Can't afford a GTX 280...plus...the performance/dollar isn't as good....
Got my EVGA 260 stock card running at FTW speeds. Seems to be stable as a rock. Played crysis and Tf2. I upped the fan speed to 55 percent.
The 260 seems to OC quite nicely.

That's what I've been thinking about and with that under its belt and the limited overclock potential of the HD 4870, at the same price point, might be able to pull the GTX 260 just ahead for those who overclock. Not to mention the 896MB frame buffer versus 512MB.
Just brainstorming here, although benchmarks may say something different.
This review is very bias against the XFX 280 "See CRYSIS results" I mena a 260 "non oced" kills a 280 every time and in every resolution!!
EDIT:- Also RV770 is said to be able to handle 1Ghz even if that an inflated amount it would still come close to 900Mhz and also the amount to DT on an Oced 4870 would be more than on a 260!!!
Just wait for non-ref. 4870's to come through and flash a 4870 with those TOXIC, etc bios!!!
Also you cant ignore 10.1 "Some keys similar to DX11" and tessellation "DX11 will use this"
I don't think 700mhz core is the norm. The max I can get my evga SC is 689 @ 60% fan speed. Also, you have to remember, there is a point where performance actully gets worse the higher you go. For instance, almost anything over 2200mhz memory and your fps will drop.
Cheex, you're gaming on a 19" LCD? If you HAVE TO have one of the two I would go for the GTX260. The resolution of a 19" monitor is what? Like 1440x900?
Yes it is 1440x900 but...the reason I'm so keen on this is that I expect to move up into the 1920x1200 territory. I want to get a 24" - 28" monitor as soon as I can. I like the Hanns-G 28"
.My GTX 260 also overclocks very poorly, it not completely stable even at FTW speeds. First I thought not getting enough power because the PCIe 1.1 slot is 75W max compared to PCIe 2.0 slot with 150W, but switching motherboards didn't make any difference. This is the first gen of video cards where the FTW edition might be a better idea if getting GTX280 performance on the cheap is your goal.
I'm running at basically the same clocks.
691/1458/1269 with an EVGA SC.
Quite a few cards hit 1512 shaders and 1300 memory. They're very dependent on temps and cooling.
a heavily oc'ed gtx 260 (lets say around 700 / 1500 / 2500) should give roughly 90-95% of the performance of a stock gtx 280.
Would you say that the OCing further negates the price difference for a GTS 280, making the GTX 260 a better purchase??
yes and no. if you are running a higher resolution such as 1920x1200 or higher then i will say that a gtx280 is better than an oc'ed gtx260 as you can oc it as well, and in higher resolutions, you will start to see a stock gtx280 pull away from a heavily oc'ed gtx260. If you are running a lower resolution then i will reccomend an oc'ed gtx260 or a 4870 (maybe even a 4850 since they are so cheap now) over the gtx280 as the difference will not be as pronounced.
